eh im too lazy to search for the safcII thread so I'll post here and you can move it if you think its valueable info....I had a fully functional and tunable SAFC working on my FSO3 turboed 95MX6...thats right i had fuel control and all...I did it by modifying the signal both into the safc and out of the safc to deal with the voltage problem. However i used a circuit board design to manage voltage, for the dynamic change part. Since the mx6 was originally N/A I didnt need to mess with modifying the o2 signal... I was able to tune stoich/slightly rich all the way to 9psi...the person i sold it to blew it at 10psi, though it was due to a worn out engine, not necessarily detonation...this was on stock injectors with a Wally 190 fuel pump....if you are still concerned about fuel the dsm 450 injectors are a perfect swap in the the fs series engines and will provide more fuel than most protege owners will ever need. You can pick them up for around 50 bucks all day long on ebay...Im fairly confident I can take care of the voltage problem if someone can handle the o2 problem(have to find my old circuit design though), this o2 problem is uncharted territory for me so. As far as the pressure switch why not just use the same thing JoeP is using for his fcd kits. its an adjustable pressure switch...
